Cellular Automata for Crypt-Steganography

The general idea behind \"Secret sharing\" is to distribute a secret (e.g., encryption/decryption key, image) to n different participants in such a way that any k participants can reconstruct the secret. Any (k - 1) or less participants can not reveal anything about the secret. Previous Secret image sharing techniques with Steganography greatly affects on the visual quality of cover images, and also authentication mechanism used needs to be improved. In proposed technique, instead of using conventional techniques for secret sharing, a linear reversible cellular automaton is used.
